What Changed

▼

Generated from git diff by delegated diff-reading agent. Code diffs are ground truth.

Infrastructure: Factory convergence loop improvements: crank lifecycle documentation in SKILL.md, hard convergence gate (ALL scenarios must pass), fix-forward commit policy for review pack rendering. Review pack renderer gains </script> escaping, dynamic SVG viewBox, zoom controls. 8 new holdout scenarios (13-20) added for pong interface behaviors. Codex prompt template updated with score_limit protected file.

Product: New interactive play module (src/play/) with two-player same-keyboard controls, agent takeover toggle, player status tags, and configurable score-limit rallies. Environment gains score_limit config for multi-rally mode (default 1 preserves RL training). Makefile adds play, play-debug, play-agent-vs-agent targets. pygame added to dependencies. 3 new test files covering play module, score-limit logic, and env smoke tests.

Factory Infrastructure

Major factory iteration: 10 files changed across skills, prompts, docs, and CLAUDE.md. Factory orchestrator SKILL.md gains crank lifecycle states (IN PROGRESS / CONVERGED / COMPLETE) and hard convergence gate — ALL scenarios must pass, no percentage threshold. Review pack renderer (render_review_pack.py) gains </script> content escaping, dynamic SVG viewBox calculation, and zoom controls. Template updated with visual inspection banner. CLAUDE.md adds fix-forward principle and factory orchestration hard rules. 8 new holdout scenarios validate play module behaviors. New spec pong_interfaces.md defines interactive play requirements. Factory feedback artifacts from iterations 0-1 and post-merge tracking included.

Environment + Play Module

src/envs/minipong.py gains score_limit config parameter and multi-rally logic — when score_limit > 1, points reset the ball instead of ending the episode. Cumulative scores tracked across rallies. Default score_limit=1 preserves existing RL training behavior. New src/play/ module (2 files, +213 lines) implements interactive pygame-based play: two-player same-keyboard controls (Q/A left, P/L right), agent takeover via Shift+A/Shift+L, player status tags, HUD score display, and game flow (ESC quit, R restart). Agent receives horizontally flipped observation when controlling right side.

Tests

3 new test files: test_play_minipong.py (+48 lines) tests GameController key mapping, takeover toggle, and status tag accuracy. test_env_minipong_score_limit.py (+44 lines) tests multi-rally continuation and score_limit termination. test_env_minipong_smoke.py (+28 lines) expanded with additional env smoke validations.

Config / Build

Makefile gains 3 new targets: play, play-debug, play-agent-vs-agent — convenience wrappers for the interactive play module. requirements.in adds pygame dependency. requirements.txt updated via pip-compile with pygame and transitive dependencies.

FileAgentsZoneNotable
src/play/play_minipong.py MAB+ environment Well-structured play module, but GameController class is large (208 lines in one file)
MAB+main
The play module implements the full spec correctly: two-player controls, agent takeover, status tags, score-limit rallies, and game flow. The GameController class handles input mapping, agent toggle, observation flipping, and rendering all in one file. While functional and tested, a future refactor could separate input handling from rendering. The agent checkpoint loading with random-policy fallback is a good defensive pattern. No gaming or hardcoded lookup tables detected.
src/envs/minipong.py MAA environment Clean score_limit addition preserves backward compatibility
MAAmain
The score_limit parameter defaults to 1, perfectly preserving existing RL training behavior while enabling multi-rally mode for interactive play. The implementation correctly resets ball position and velocity using the episode RNG after each point, maintaining determinism. Cumulative score tracking is clean. The change is minimal (+46/-8) and surgical.
tests/test_play_minipong.py MAB+ tests Tests exercise real GameController, no mocking of system under test
MAB+main
Tests instantiate the actual GameController and verify key mappings, takeover toggle, and status tag content. No mocking of the system under test — tests call real methods and assert real outputs. Coverage includes both human and agent control states. Could benefit from edge-case tests (e.g., simultaneous key presses, rapid toggle sequences) in a follow-up.
tests/test_env_minipong_score_limit.py MAA tests environment Anti-vacuous test: runs real env to score_limit, validates episode_reason
MAAmain
Tests create a real MiniPongEnv with score_limit=11, step through until termination, and verify multiple points were scored and episode_reason == 'score_limit'. No stubs, no mocking the env. The test proves multi-rally mode works end-to-end.
tests/test_env_minipong_smoke.py MAB+ tests environment Extended smoke test covers observation shape, dtype, and basic stepping
MAB+main
Expands the existing smoke test with additional assertions. Tests use real env instances, no mocking. Clean and focused.
specs/pong_interfaces.md MAA factory Comprehensive spec covers controls, rendering, scoring, agent takeover, status tags
MAAmain
The spec is thorough and unambiguous: key mappings in a table, rendering requirements with specific pixel sizes, scoring rules with configurable limit, agent takeover controls, status tag content for all states, and Makefile targets. This is a well-written spec that leaves minimal room for misinterpretation.
Makefile MAB+ config Clean Makefile additions for play targets
MAB+main
Three new targets (play, play-debug, play-agent-vs-agent) follow the existing Makefile pattern. Commands use python -m src.play.play_minipong module invocation, consistent with the project convention.
.claude/skills/factory-orchestrate/SKILL.md MAA factory Crank lifecycle and hard convergence gate are critical process improvements
MAAmain
Adds three-state crank lifecycle (IN PROGRESS / CONVERGED / COMPLETE) and removes the percentage-based satisfaction threshold in favor of ALL-scenarios-must-pass. This is a significant process hardening — it prevents partial convergence from being declared as success. The fix-forward principle is also codified here.
.claude/skills/pr-review-pack/* MAB+ factory Review pack renderer fixes: script escaping, dynamic viewBox, zoom controls
MAB+main
The renderer gains three important fixes: (1) </script> in embedded content is escaped to <\/script to prevent HTML parsing breakage, (2) SVG viewBox is calculated dynamically from zone positions instead of hardcoded, (3) zoom controls (+/-/Fit) added to template. These are systemic fixes that prevent recurring rendering issues.

MAN/Amain
This is a generated HTML review pack (3710 lines). It is an output artifact of the review pack renderer, not hand-written code. Excluded from adversarial review.

Key Decisions

▼
1
New spec-driven module: interactive play via pygame
The pong_interfaces spec defines a complete interactive play experience that required a new src/play module

Rather than extending the existing environment with interactive rendering, a separate src/play/ module was created. This keeps the RL training environment clean (headless, single-agent, score_limit=1) while the play module handles human interaction, two-player controls, agent takeover, and multi-rally scoring. The play module imports from src.envs.minipong for game physics and from the RL modules for agent policies.

2
score_limit=1 default preserves RL training backward compatibility
Multi-rally mode must not break existing training pipeline which expects single-point episodes

The score_limit parameter was added to MiniPongConfig with a default of 1, meaning existing code (training, evaluation, all 12 original scenarios) sees no behavioral change. Only the interactive play module sets score_limit=11 for multi-rally games. This is a classic additive-only API extension — new behavior is opt-in.

3
Agent observation flip for right-side play
Trained agents always see themselves on the left — right-side agent needs flipped observation

When a trained DQN agent takes over the right paddle, the 84x84 observation is horizontally flipped before being fed to the policy. This ensures the agent always perceives itself as the left paddle, matching its training perspective. Without this flip, a trained checkpoint would make incorrect decisions when playing from the right side.

environment
FileChange
src/play/play_minipong.pyHorizontal flip via np.flip for right-side agent observations
4
Hard convergence gate: ALL scenarios must pass
Percentage-based thresholds allowed partial failures to slip through as 'converged'

The factory orchestrator SKILL.md was updated to remove the satisfaction percentage threshold. Convergence now requires ALL scenarios passing — a single failure blocks convergence regardless of cause (regression, merge conflict, pre-existing). This was learned from a near-miss where scenario 7 was failing pre-merge but the percentage threshold would have allowed it through.

.claude/skills/factory-orchestrate/SKILL.mdRemoved satisfaction threshold, added ALL-pass requirement

5
Fix-forward review pack renderer for production resilience
Template and renderer had recurring issues that would break every future review pack

Three systemic renderer fixes: (1) </script> in embedded file content breaks HTML parsing — now escaped as <\/script. (2) SVG viewBox was hardcoded — now dynamically calculated from zone positions via _calculate_viewbox(). (3) Added zoom controls (+/-/Fit) to the architecture diagram. These are fix-forward changes: instead of patching individual review packs, the renderer itself was fixed so all future packs are correct.

6
8 new holdout scenarios validate pong interface behaviors
The new play module needed behavioral coverage beyond unit tests

Scenarios 13-20 were added as holdout evaluation criteria for the pong interfaces spec. They cover: play module importability, Makefile targets, two-player keyboard controls, agent takeover toggle, player status tags, continuous multi-rally play, right-side observation flip, and pygame dependency. These scenarios are factory-protected — the coding agent (Codex) never sees them.

Gate 2 — NFR
PASS
All 20 holdout scenarios pass — 12 original + 8 new pong interface scenarios
Environment scenarios (1-5, 15-19): all pass — determinism, observation space, rewards, rendering, info dict, controls, takeover, status tags, continuous play, observation flip. Training scenarios (6-7): artifacts and videos produced. Pipeline scenario (8): verify-learning runs. Dashboard scenario (9): importable. Integration scenarios (10-14, 20): env-smoke, lint/typecheck, e2e pipeline, play module imports, Makefile targets, pygame dependency — all pass. 100% satisfaction.
Gate 3 — Scenarios
20/20 (100%)
20 of 20 holdout scenarios pass.
Overall
NOT READY
Gates not all passing. 20/20 scenarios.
Gate 1 (deterministic): CI 5/5 passing. Gate 2 (NFR): no findings. Gate 3 (behavioral): 20/20 scenarios passing. The pong interfaces factory crank converged in 2 Codex iterations plus validation. All product code is tested, all factory infrastructure improvements are fix-forward. No post-merge blockers remain.

Post-Merge Items

▼
MEDIUM Add src/play/ to zone registry

The new src/play/ module does not match any existing zone in .claude/zone-registry.yaml. Currently the play files are orphaned from the architecture diagram. They should either get their own zone or be added to the environment zone's paths.

## .claude/zone-registry.yaml, lines 2-4 environment: paths: ["src/envs/**"] # should also include "src/play/**" or create a new zone
Failure scenario
Future review packs will show src/play files as unmapped, and the architecture diagram will not reflect the play module.
Resolution
Zone registry includes src/play paths, architecture diagram accurately shows the play module's relationship to the environment zone.
factory environment
LOW Extract GameController rendering from input handling

The GameController class in src/play/play_minipong.py (208 lines) handles input mapping, agent toggle, observation flipping, score display, status tags, and the main game loop all in one class. A future refactor could separate concerns.

Failure scenario
As features are added (e.g., network play, replay recording), the class becomes unwieldy and hard to test in isolation.
Resolution
Input handling, rendering, and game logic are in separate classes/files, each independently testable.
environment
COSMETIC FFMPEG macro_block_size warnings in evaluation videos

Every scenario that produces videos logs IMAGEIO FFMPEG_WRITER WARNING: input image is not divisible by macro_block_size=16, resizing from (84, 84) to (96, 96). While not a functional issue, the warnings clutter scenario output.

Failure scenario
CI logs are noisy and make it harder to spot real warnings.
Resolution
Either the frame size is padded to 96x96 before writing, or macro_block_size is set to 1 in the imageio writer call.

Timeline

Spec + Scenarios Written
Human (Joey)
pong_interfaces.md spec created. 8 new holdout scenarios (13-20) added covering play module, controls, agent takeover, status tags, continuous play, observation flip, pygame dependency.
Commit: fea198a . Feb 26
The spec defines two-player same-keyboard controls (Q/A left, P/L right), agent takeover (Shift+A/L), player status tags, configurable score-limit rallies, and Makefile integration. Scenarios are behavioral holdouts — Codex never sees them.
Iteration 0: Seed Feedback
Factory (orchestrator)
Initial seed feedback compiled from spec analysis. Codex receives pong_interfaces.md spec and iteration 0 feedback.
Commit: a511e36 . Feb 26
Seed feedback highlights key implementation requirements: score_limit config, two-player controls, agent takeover toggle, observation flip for right-side agent, pygame dependency.
Iteration 1: Codex Implementation
Codex (attractor)
Codex produces initial pong interfaces implementation. Gate 0 review finds API mismatches in GameController.
Commit: 521d8cd -> 2d0f270 . Feb 26
Codex creates src/play/play_minipong.py, src/play/__init__.py, modifies src/envs/minipong.py for score_limit, adds tests and Makefile targets. Gate 0 adversarial review identifies GameController API mismatches (method signatures don't match how scenarios call them). Gate 0 blocks — feedback compiled for iteration 2. 12/20 scenarios passing (60%).
Gate 0 Failure: Merge + Feedback (Fix-Forward)
Factory (orchestrator)
Gate 0 blocked iteration 1. Per factory rules: Codex's code is merged (not reverted) so iteration 2 builds incrementally.
Commit: c803919 -> cc7bb06 . Feb 26
Initial reaction was to revert (commit 0634725), but factory rules require keeping Codex's code for incremental iteration. Revert was reverted (cc7bb06). Fix-forward policy codified: on Gate 0 failure, merge code, compile feedback, iterate — never revert. This incident led to adding the fix-forward principle to CLAUDE.md.
Iteration 2: Codex Fixes
Codex (attractor)
Codex fixes GameController API mismatches from Gate 0 feedback. All 20 scenarios now pass.
Commit: 7ff1b03 -> 886cd45 . Feb 26
Codex receives iteration 1 feedback detailing the API mismatches. Fixes applied to GameController method signatures. Gate 0 passes. Gate 1 passes (lint, typecheck, tests). Gate 3: 20/20 scenarios passing. Satisfaction: 100%.
Scenario 18 Fix + Holdout Restoration
Factory (orchestrator)
Scenario 18 (continuous play) had score_limit=11 mismatch — fixed. Holdout scenarios restored after Codex isolation.
Commit: ad8d2ce -> 27f5726 . Feb 26
Scenario 18 was testing multi-rally with score_limit=11 but the test setup had a mismatch. Fixed to properly set score_limit config. Holdout scenarios (stripped before Codex runs) restored to factory branch.
Factory Rules Hardened
Human (Joey) + Factory
CLAUDE.md updated with non-negotiable factory orchestration rules: Gate 0 agent teams, no reverts on failure, branch cleanup.
Commit: e54a161 -> 7b81ee8 . Feb 26
Lessons from the revert incident codified: (1) Gate 0 MUST use agent teams via TeamCreate — no shortcuts. (2) On Gate 0 failure, merge Codex's code for incremental iteration — never revert. (3) Delete Codex's remote branch immediately after every merge. These are written as hard constraints in CLAUDE.md.
PR Created + Review Pack Generated
Factory (orchestrator)
PR #9 created. Review pack generated with Pass 1 diff data, Pass 2 semantic analysis, Pass 3 HTML render.
Commit: 7df73d3 . Feb 27
Factory convergence achieved: 20/20 scenarios, CI 5/5, all gates pass. PR created from df-crank-v01-pong-interfaces to main. Review pack generated using the three-pass pipeline.
Fix-Forward: Review Pack Rendering Fixes
Factory (orchestrator)
Final fix-forward commit: renderer escapes &lt;/script&gt;, dynamic SVG viewBox, zoom controls, convergence hard gate.
Commit: aff7512 . Feb 27
During review pack generation, three rendering issues were discovered and fixed at the renderer level (not patched in the output): (1) </script> in embedded content breaks HTML — renderer now escapes it. (2) SVG viewBox hardcoded — now calculated dynamically. (3) No zoom controls on architecture diagram — added. Also codified the convergence hard gate (ALL scenarios must pass) in the factory orchestrator skill. This is a factory-infrastructure-only commit — no product code touched.
